3.1 PIAGET’S THEORY OF COGNITIVE DEVELOPMENT

Swiss psychologist Jean Piaget (1896-1980) developed a model describing how human go about making sense of their world by gathering and organizing informations. This idea provide an explanation of the development of thinking from infancy to adulthood.

According to Piaget, certain ways of thinking are simple for an adult but are not simple for a child. For example Piaget asked a 9-year old:

“What is your nationality?

  • I am Swiss.
  • How come?
  • Because I live in Switzerland
  • Are you also a Genevan.
  • Not that’s not possible I am already Swiss, I can’t also be Genevan.

Some times all you need to do to teach a new concept is to give students a few basic facts as back ground. In other times, however, all the facts in the world are use less. The students simple are not ready to learn the concept. Like the 9- year old above, they have trouble with classifying one concept (Geneva) as a subset of another (Switzerland). They may think that they will some day cross the ages of their brothers and sister. They may also confuse the past and future.
